    Abstract: A fiber laser oscillator comprises an active fiber for providing a lasing light having a selected wavelength band, a saturable absorber assembly coupled to a first end of the active fiber, a pump source for providing a pump light having wavelengths except the selected wavelength band, an optical component coupled to the second end of the active fiber and the pump source. The optical component comprises a thin film filter for transmitting the lasing light for a first time and reflecting the pump light and a reflector for reflecting the lasing light transmitted for the first time through the thin film filter. The lasing light reflected by the reflector transmits through the thin film filter for a second time and overlaps with the pump light reflected by the thin film filter.
